Random-modulation cw (RM-CW) lidar has characteristics that make it possible to use a small-power cw laser as the light source. Development of laser diodes (LD) has been very rapid recently. The laser diode is compact in size and can be driven with little energy compared with traditional lasers, so that it is the most promising candidate for use in a portable, compact and practical lidar system. In this paper, a prototype portable RM-CW lidar system with an LD light source is reported. This is the first report of a practical LD system, to the authors' knowledge. Measurements of the spatial aerosol profile up to several hundred meters, as well as cloud ceiling-height up to several kilometers, were detected, at night time with this system and are shown in this paper.
